Rolling bearing thin oil lubricating structure

Abstract

The invention relates to a rolling bearing lubricating structure with thin oil. The two ends of the inner ring of the rolling bearing (13) are clamped respectively on the inner collar (14) and the outer collar (5) of the rotating shaft (4), and the inner collar (14) and the outer shaft The ring (5) positions the inner ring of the rolling bearing (13), the outer ring of the rolling bearing (13) is installed at the bearing stop (10-2) in the bearing sleeve (10), and the bearing inner cover 11 and the bearing outer cover 2 pass through the bearing cover The fastener 8 is fixed on the bearing sleeve 10 and positions the outer ring of the rolling bearing 13. Two pieces of O-shaped rubber rings 7 are respectively installed in the sealing grooves 10-1 at both ends of the bearing sleeve 10, and the sealing cover fastener 6 is used to seal the inner The sealing cover 12 is fixed on the bearing inner cover 11 . The invention has the advantages of large bearing capacity, high working speed, reliable operation, etc., can improve the reliability of the equipment as a whole, and effectively reduce repair and maintenance costs.

Description

technical field [0001] The invention relates to a thin oil lubricating structure of a rolling bearing. Background technique [0002] Most of the rolling bearings used in motors or other rotating equipment are grease lubricated. Grease lubrication has the advantages of simple structure, low manufacturing difficulty, and easy maintenance. For equipment with a poor operating environment, complex loads during operation, especially high operating speeds, the grease-lubricated bearing structure is difficult to meet the operating conditions of the equipment. Bearings lubricated with grease have a relatively simple structure. In a dusty environment, dust can easily enter the interior of the bearing, which can easily cause mechanical failures such as lubrication failure and bearing burnout. When the ambient temperature is high, due to the low heat dissipation of the grease-lubricated bearing, long-term operation will also cause the failure of the bearing to burn out. Due to the hig...

AI Technical Summary

Problems solved by technology

For equipment with poor operating environment and complex loads during operation, especially when the operating speed is high, the grease-lubricated bearing structure is difficult to meet the operating conditions of the equipment.

The structure of the bearing lubricated by grease is relatively simple. In the environment with a lot of dust, the dust is easy to enter the inside of the bearing, which may easily cause mechanical failure such as lubrication failure and bearing burnout.

When the ambient temperature is high, due to the low heat dissipation of the grease-lubricated bearing, long-term operation will also cause the failure of the bearing to burn out

Due to the large friction coefficient of grease lubrication, the bearing generates a lot of heat during high-speed operation, resulting in bearing burnout
